Clamping off the end of the foreskin and urinating into the void created around the tip of the penis, then releasing the built up pressure of urine in the foreskin all at once.
The Danish military teaches the P bomb as a matter of field hygeine to its uncircumsized troops. in order to sterilize the foreskin with urine and prevent infection, but its also a really fun thing to do at parties to show losers that dont have foreskins.
